PERFORATION-SPACING DEVICE.

SPECIFICATION forming part of Letters Patent No. 738,852, datedSeptember 15, 1.903. i ik Application led February 24, 1903. Serial No.144,855. (No model.)

To all whom it ntay concern:

Be it known that I, ALeERNoN S. SEvILLE, a citizen of the United States,residing at Memphis, Shelby county, State of Tennessee, have inventedcertain new and useful Improvements in Perforation-Spacing Devices, of4

or for the stencil-sheets to be used in the manu'facture of suchtune-sheets.

The objects of my invention are, first, to provide a simple andefficient metronome which will be capable mechanically of adjustnientwithout technical knowledge of the subject; second, to provide ametronome which will accommodate the entire possible range of tempo inmusic; third, to provide simple means of shaping the sheet ready forinsertion in the device and in the piano-player; fourth, to provide anefficient yet simple clamp for the sheet 5 fifth, to provide a scale foraccidentals; sixth, to provide means of preventing accidental cutting ofnotes in the wrong spaces, and, seventh, toA generally improve t iedetails of these parts.

I accomplish these objects, as will be more fully hereinafter set forthin the drawings, specification, and claims.

Figure 1 is a plan of the device. Fig. 2 is a sectional elevation on theline II ll of Fig. 1 looking in the direction of the arrow. Fig. 3 is asectional elevatioiifon the line Ill Ill of Fig. 1 looking in thedirection of the arrow. Fig. 4t is a plan and elevation of a detail.Figs. 5, G, and 7 show manner of arranging the cross or metronome cordsfor three-four, four-four, and six-four time, respectively. y

Referring now tothe drawings, in which like numerals indicate the sameor like parts in all the views, 1 1 are side pieces of a frame, (nototherwise shown,) which supports a number of wires 2, spaced equally andof a distance apart corresponding with the space between the holes inthe tracker-board of the player on which the sheet is to be used.

time.

lf, for instance, there are fty-six to be operated by the player, theremust be fifty-six spaces, and therefore fifty-seven wires, on theperforator. A smaller number is shown for purposes of convenience only.The method of supporting the wires and the sheet to be operated on ismore fully set out in my Patent No. r120,075, dated February l0, 1903,for a perforation-spacing device.

3 is a scale by which each space between ,wires is designated. Thisscale has a plurality of faces 4., any one of which may be placed as isthe one here shown, but which is not described, since it is not desiredto make it a part of this application. In this scale, however, middle Cis marked by an arrow or other indicator, as shown, and the base andtreble clefs are also indicated. Coming directly in front of the edge ofthe face e of this scale is a fixed wire 5, which is stretched across atright angles to the wires 2, which give the pitch, which wire serves asan index or base for the tempo-divisions. (i 6 are elastic bandsstretched across parallel to this base-wire, which divide the spaceslongitudinally or for time. As shown, these bands give two beats or asingle measure of two-two or two-four These bands 6 are carried at eachend by notched pins 7 the shanks 8 of which connect together pieces 9 10to form lacy-tongs,

one foreach side of the device. These shanks extend downward below thepieces 9 10 and rest in a groove 11, in which they are free to slide.The piece 9, however, at the left end of each pair of the tongs isfastened into `the frame, asvshown. This is preferably effected by usinga screw l2, the notch in the head of which serves as a rest for theindexwire 5. The piece 10 at the right-hand end of each pair of thetongs is fastened by their pin-Shanks S into racks 13, which slide inthe same grooves 11 as do the said pin-shanks and which are moved bypinions 14 on a shaft 15, actuated by a thumb-wheel 16.

17 is a pointer on one of the racks 13, and 18 is a scale, preferablymarked, as shown, Allegro,7 Allegro moderato, Andante, and Larga Vhen,therefore, the music is written Allegro, the scale-pointer 17 is broughtto this position. If written in other time,. it is brought to theposition desired, thus mechanically relieving the operator of IOOtrouble in the matter. As will be seen, the lazy-tong movement willproportion the distance between the pins 7, and therefore willgive'equal spaces between each, and therefore between the bands on same.Since, also, the index-wire is placed on one of the pins, the spacebetween it and the cross-bands and between the cross-bands themselves isequal. The pointer 17, therefore, being moved, the spaces between thebands and between the index and bands increases or decreasesproportionately.

19 is a casing to cover and hold down the outer ends of the lazy-tongs.This casing is shown removed on one side of the device to show theentire tongs. If desired to use this spacing device for more than sixbeats, the tongs .may be extended to the dotted position shownv andbands strung on the pins 7 and also on the center rows of pins 20,thereby giving, if desired, twelve beats of twelve-eight time or anydesired lesser number. It would be possible also to cut faster or slowertime than the ordinary range of the device by this means. In Fig. 5 Ishow the arrangement of the cross-bands G for three beats or one measureof three -four or three-eight time. Fig. 6 shows the same arrangementfor four beats or one measure of four-four or foureight time. Fig. 7shows a measure of sixfour or six-eight time. Fig. 4 shows a planelevation and end elevation of a modified form 10n of the top piece ofthe lazy-tongs. In this a lug 20 is punched and turned up in lieu of thepin 20, and the end 7 is turned up instead of the pin 7. The pieces 9and 10 are then riveted together. In this case it is necessary to getthe pieces 2O,L and 7 as nearly as possible over the rivets in orderthat their proportionate distance from the index-wire 5 may remain asnearly constant as possible.

21 is a fixed scale having the scale-letters A, B, C, D, E, F, G inorder corresponding with the white keys of the piano, and the black keys(the sharps and dats) represented by shaded sections. This scale is usedfor accidentals. The paper is held for cutting by a clamp comprising acylindrical casing 22, having an inturned iiange at the bottomsupporting a spring 23, which bears against the under side of thebutton-head 24L on a pin 25. This pin is depressed by a cam 26, pivotedat 27 and having an arm 28, extending outward therefrom. This cam ispreferably so located with reference to the button 24 that it releasesit entirely only when straight out over the cutting-board of the device,so that it will interfere to a greater or less extent with the operationof perforating the paper unless the same is locked. This locking is doneby swinging the arm in the direction of the arrow about ninety degrees,and thereby depressing the pin 25.

29 is atriangular sheet of metal shaped to conform to the required shapeof the ends of the paper to be used in the piano-player, which issupported at one or both sides j ust clear of the board 30, which servesas a music-rest. The end of the paper is slipped under this from oneside or one end, as the case may be, and is then torn by this piece tothe desired shape. In use the paper is pointed as just described, anydesired fastenings are put on it, and it is slipped to place beneath thewires 2. The arm 28 is then moved to clamp the paper, the desired numberof cross-bands are placed,and the pointer 17 is moved to the desiredtime, as shown by the tempo-scale 18. The several notes constituting themeasure are then cutin their proper positionsas regardspitch and timeand the clamp is loosen ed and the paperslipped forward until the lastnote cut comes against the index-wire. the operation repeated.

In order to guard against the danger of cutting a note against theindex-wire, and therefore incorrectly, I provide a strip of celluloid3l, which iills the space between the indexwire 5 and the first band 6.This strip being transparent permits the wires to be seen be- The clampis then reset and neath it and therefore easily followed from thepitch-scale. 32 is the ypaper to be cut.

Having fully described my invention, what I claim, and desire to secureby Letters Patent of the United States, is-
